Company statement
The reliability of "Scince Purge" testing equipment has been recognized by many customers, especially 1406D, 1406YO, 1802D, 1802YO and other models are favored in the second-hand market. Recently, we have received feedback from the market that due to poor use and maintenance, improper operation of untrained personnel,etc, the following problems have occurred. Including the internal parameters of the equipment are confused, the circuit board is corroded, tetc. In addition, we found that some employees who left our company continued to engage in the after-sales service without our authorization, and resell second-hand "Scince Purge" equipment. The above situation will not exclude the behavior of modifying some internal parameters of the equipment in violation of the principles of our company, which will inevitably lead to the distortion of the test results. Therefore, our company decide to take measures helps the end users to identify and avoid the adverse mpact of such events on users.

Unreliable static electricity--Standards for electrostatic discharging
Air filtration materials such as meltblown fabric and electrostatic cotton are electrically charged by means of water electret and electric electret in order to obtain high efficiency. Materials such as glass fibre and PTFE, and filters made of them, can also become electrically charged for various reasons. These electrostatic charges are not completely reliable and will decay over time and with the environment changes, thus affecting the filtration efficiency of the masks and filters. Therefore, the effect of static electricity on the filtration efficiency of filter materials, masks and filters needs to be examined.
